14 digital dry contact inputs module (WBIO-DI-DR-14)
Внимание: Отображаемое название «14 digital dry contact inputs module (WBIO-DI-DR-14)» переопределяет ранее заданное отображаемое название «WBIO-DI-DR-14 I/O Module». The model is discontinued. Recommended replacement is WBIO-DI-WD-14
Purpose
Connection of pulse counters, buttons, switches, sensors with dry contact output.
Technical specifications
It contains 14 inputs for connection of dry contacts, which are united in two groups of 7 inputs with group galvanic isolation. The scheme of inputs is shown in the figure. The terminal is supplied with ~ 4.5 V, when the small (1 mA) current is supplied to the ground, causing the operation of the input.

Connection to controller
See activating the module in the web interface of the controller.
Connection
Sensors/counters with pulse outputs/buttons.
Such devices form a signal by closing two wires that are suitable for them. Connect one wire to the GND terminal of the module. Connect the second wire to the Dx terminal. Some counters have a pulse output on the optocoupler, then the two wires have a polarity - "plus" and "minus". In this case, minus is connected to GND, plus to Dx.
Devices with open collector output.
Устройство и модуль должны иметь общую землю. Выход "открытый коллектор" подключите к клемме Dx.
Входы модуля гальванически развязаны от контроллера. Поэтому земли GND модуля и контроллера могут быть разными.
